DOVER — Murder suspect Seth Mazzaglia was ordered to be held without bail Monday during his arraignment on charges relating to the death of University of New Hampshire student Elizabeth “Lizzi” Marriott.Dover Circuit Court Judge Stephen Morrision said Mazzaglia faces a felony second-degree murder charge for strangling and/or suffocating Marriott on October 9. “What it alleges,” Morrison said, “Is that on October 9 you recklessly caused the death of Elizabeth Marriott under circumstances manifesting in extreme indifference to the value of human life by strangling her and/or suffocating her.” The crime is alleged to have occurred in Mazzaglia's apartment on 1 Mill Street in Dover.Mazzaglia, who's currently held at the Strafford County House of Corrections, is due to appear in court for a probable cause hearing on October 29 at 10 a.m. Morrison, who entered no plea on Mazzaglia's behalf, said the defendant has already filled out a petition for legal counsel. Morrison also announced the state will allow Mazzaglia's attorney an opportunity to view the affidavit attached to warrants authorizing police to arrest Mazzaglia and search his apartment over the weekend. This information, which will be divulged to the public defenders office, will not be made public to anyone other than Mazzaglia and his legal counsel.

Attorney General Jane Young requested Mazzaglia be held without bail for an offense that can possibly result in a life sentence. Later Monday afternoon, Young announced marine patrol was still searching for Marriott's body in the area near Lookout Point at Peirce Island based on credible information previously obtained by investigators. She announced strong currents in the area off Peirce Island had made the search increasingly difficult, but announced investigators were using sonar equipment and underwater cameras to aid their recovery efforts. She said the search may last several more days.“We have not discussed an end date,” she announced at approximately 3:30 p.m. across from the Dover Circuit Court. “We have discussed continuing with this until we find her.”Young also announced the Dover Police Department is now leading the investigation into Marriott's death and disappearance. She urged anyone with information pertaining to the case call the police department at 603-742-4646. Those individuals who wish to remain anonymous may call the Dover Crimeline at 603-749-6000.Marriott was last seen Tuesday night while attending a class at the UNH Durham campus. According to Anthony Hanna, Marriott's uncle, his niece told a friend she was leaving UNH at 9 p.m. and heading to the home of a female friend in Dover on Mill Street. Marriott reportedly never arrived at the home.Hanna said police discovered Marriott's phone sent two more transmissions on Tuesday evening — one at about 9:30 p.m. and another at about 10:10 p.m. The last transmission was sent from a cell phone tower in Dover, according to Hanna.Portsmouth and state police began searching for Marriott's body in the area around Peirce Island and Prescott Park beginning at approximately 7:30 p.m. Friday. Despite a search effort lasting throughout the night and into Saturday, investigators were unable to locate Marriott's body. The search was called off on Sunday due to dangerous water conditions.On Saturday, Assistant Attorney General James Vara announced Marriott's vehicle, a 2001 tan colored Mazda Tribute, was located at a UNH parking lot. He said investigators were combing Marriott's vehicle for clues and stressed other UNH students were not at risk.“I want to confirm there are no other threats to the other students at UNH,” he said. “This is unrelated other than the fact she's a student at the university.”Citing an ongoing investigation, Vara offered minimal details in terms of Mazzaglia's role in Marriott's disappearance. Although he stated the two knew each other, he could not provide information such as Mazzaglia's address or where he works. Mazzaglia is a UNH alumnus.Vara also declined to address whether police presence at an apartment on Mill Street in Dover late Friday night was also linked to Marriott's disappearance. A Dover crime van and two police cruisers were seen exiting an apartment at 1 Mill Street and had taped off a dumpster in close proximity to the building.Mazzaglia appears to have been the operator of a website located at www.sjmazzaglia.com.

She attended Manchester Community College her freshman year before transferring to UNH this year. She was living with her aunt and uncle in Chester, N.H. and commuting to UNH to save money.Hanna described his niece as an “all-around nice kid,” who was quiet and loved to read.“She's a very nice person,” he said. “She's a very pretty girl, which is — she's also, I would say, a little bit young and naive. When you're at that age, life is great and everyone's your friend. She's a very trusting person. But (she has) a good outlook on life.”The web domains FindLizzi.com, FindLizzie.com, and FindLizzy.com have all been bought by Marriott's family.
